    • This invention relates to novel benzopyran and other benzo-fused leukotriene B4 (LTB4) antagonists of formula (I), and the pharmaceutically acceptable salts thereof, wherein A is O, CH2, S, NH or N(C1-C6)alkyl; R is hydrogen or hydroxy; A is (a), (b) or (c); R is selected from the group consisting of tetrazolyl, carboxy, cis or trans -(CH2)m-CX =CX -CO2H, -(CH2)mCX X X , -CO-NG G , (d), and a substituted five or six membered aromatic ring optionally having one or two heteroatoms where the heteroatoms are optionally independently selected from the group consisting of O, S and N; R is hydrogen, fluoro, chloro, (C1-C6)alkyl, (C1-C6)alkoxy, (C1-C4)perfluoroalkyl, (C1-C4)perfluoroalkoxy, (C1-C6)alkylthio, (C1-C6)alkylsulfinyl, phenylsulfinyl, (C1-C6)alkylsulfonyl or phenylsulfonyl; to pharmaceutical compositions containing such compounds or a pharmaceutically acceptable salt thereof, and to methods of using such compounds as LTB4 antagonists. The compounds and the pharmaceutically acceptable salts of this invention inhibit the action of LTB4 and are therefore useful in the treatment of LTB4 induced illnesses such as inflammatory disorders including rheumatoid arthritis, osteoarthritis, inflammatory bowel disease, psoriasis and other skin disorders such as eczema, erythema, pruritus and acne, stroke and other forms of reperfusion injury, graft rejection, autoimmune diseases, asthma, and other conditions where marked neutrophil infiltration occurs.
    • 本发明涉及式(I)的新型苯并吡喃和其它苯并稠合白三烯B4(LTB4)拮抗剂及其药学上可接受的盐,其中A 1是O,CH 2,S,NH或N(C 1 -C 6) 烷基; R 3是氢或羟基; A <2>是(a),(b)或(c); R 1选自四唑基,羧基,顺式或反式 - (CH 2)m -C CX 1 = CX 2 -CO 2 H, - (CH 2)m C X 3 X 4 X 5,-CO-NG 1,G 2,(d)和任选具有一个或两个杂原子的取代的五元或六元芳族环,其中杂原子任选地独立地选自O,S和 N; R 2是氢,氟,氯,(C 1 -C 6)烷基,(C 1 -C 6)烷氧基,(C 1 -C 4)全氟烷基,(C 1 -C 4)全氟烷氧基,(C 1 -C 6)烷硫基,(C 1 -C 6 )烷基亚磺酰基,苯基亚磺酰基,(C 1 -C 6)烷基磺酰基或苯基磺酰基; 涉及含有这些化合物或其药学上可接受的盐的药物组合物,以及使用这些化合物如LTB4拮抗剂的方法。 本发明的化合物和药学上可接受的盐抑制LTB4的作用,因此可用于治疗LTB4诱导的疾病,例如炎症性疾病,包括类风湿性关节炎,骨关节炎,炎性肠病,牛皮癣和其它皮肤疾病如湿疹,红斑 ,瘙痒和痤疮,中风和其他形式的再灌注损伤,移植排斥反应,自身免疫性疾病,哮喘和其他出现明显中性粒细胞浸润的病症。
